A Portuguese mortgage (crédito à habitação) is not just about finding the lowest advertised interest rate. The bank assesses you, the property and the structure of the loan, while you need to compare the total cost, rate risk, insurance, linked products, early-repayment terms and whether the approval actually fits the purchase timetable. This guide explains the process and gives direct links to five of Portugal’s largest banks and two established credit-intermediation services.

Start with Banco de Portugal’s rules, not a bank advertisement

The Banco de Portugal solvency guidance explains the supervisory limits banks normally work within. For a loan to buy a borrower’s own permanent home, the recommended LTV ceiling is generally 90%; for other purposes it is generally 80%. The property value used for this calculation is the lower of the purchase price and the bank valuation. The total DSTI — monthly debt payments compared with net monthly income — should generally not exceed 45%, subject to the framework’s permitted exceptions.

These are supervisory limits, not a promise that a bank will lend that much. A bank can apply stricter underwriting, and its valuation can create a larger cash requirement than you expected.

The valuation gap can change your required deposit

Suppose you agree to buy for €250,000 but the bank values the property at €220,000. A percentage limit is applied to the lower €220,000 figure, not automatically to the €250,000 purchase price. You therefore need enough cash not only for the unfinanced part of the property but also for purchase taxes, registration/completion costs and other expenses. Never assume “90% mortgage” means you only need 10% of the asking price.

Pre-approval is useful — but it is not final property approval

An early affordability/pre-approval assessment can tell you roughly what a lender may consider based on your income and debts. Final approval normally also depends on the chosen property, valuation, legal/security checks and updated documentation. If your purchase depends on finance, make sure the CPCV is drafted with an appropriate financing condition rather than assuming an online simulation or preliminary indication protects your deposit.

Documents banks commonly want

  • Identification and Portuguese NIF.
  • Evidence of address/residence status where relevant.
  • Employment contract, payslips and/or employer evidence for employees.
  • Tax returns and business/self-employment evidence where applicable.
  • Recent bank statements and information about existing debts.
  • Evidence of savings/equity and the source of funds.
  • Property documents once you have chosen the home.

Non-residents, foreign-income applicants, company owners and self-employed buyers often need additional evidence and translations. Ask each lender for its current checklist before assuming documents accepted by one bank will satisfy another.

Fixed, variable and mixed rates

  • Variable rate: normally consists of an index such as Euribor plus the bank’s spread. Payments can rise or fall as the index resets.
  • Fixed rate: the contractual rate is fixed for the agreed fixed-rate period, giving greater payment certainty but with different pricing and early-repayment implications.
  • Mixed rate: commonly fixes the rate for an initial period and then switches to a variable formula.

Do not compare offers on spread alone. Compare the TAEG, total amount payable (MTIC), monthly payment under the relevant scenario, fees, insurance costs and linked-product conditions shown in the bank’s standardised pre-contract information.

Linked products can make the headline rate misleading

A bank may offer a lower spread or rate if you maintain products such as a current-account package, salary deposit, cards or insurance. Compare both the discounted and non-discounted position and ask what happens if you later stop meeting a condition. Life insurance and multi-risk/home insurance can be a material part of the overall cost.

Five major banks to compare

By total assets in the latest available sector table (December 2025), the five largest significant banking institutions were Millennium bcp, Caixa Geral de Depósitos, Santander Totta, novobanco and Banco BPI. That ranking is included only to give newcomers a practical comparison set; it is not a recommendation that the largest bank will offer you the best mortgage.

Rates and campaigns change frequently. Use these links to obtain current simulations and then compare like-for-like amounts, terms, rate structures and product bundles rather than copying a promotional TAEG from a different example borrower.

Mortgage intermediaries: useful, but verify the registration

A credit intermediary can help present or compare credit proposals and assist with the application process. The credit itself is still granted by an authorised lender. Banco de Portugal states that credit intermediaries must be authorised/registered; use its official authorised-intermediary register to verify the exact legal entity before supplying sensitive documents.

  • Doutor Finanças — Portuguese credit intermediary; its consumer disclosure identifies Banco de Portugal registration no. 0000420. Check the current register and its lender relationships when applying.
  • MAXFINANCE — national credit-intermediation network. Individual network entities disclose their own Banco de Portugal registration and lender agreements; verify the particular intermediary you deal with.

An intermediary can save time, particularly when your income is foreign or your case is less standard, but it does not remove the need to read the bank’s own offer and standardised information. Also ask which lenders the intermediary actually works with: “comparison” does not necessarily mean every bank in Portugal.

Resident versus non-resident and foreign income

Portuguese banks can lend to non-residents and people earning abroad, but underwriting, maximum LTV, required documents and pricing can differ by bank and applicant. Currency matters too: if your income is not in euros, exchange-rate movements can change the real burden of a euro mortgage. Ask explicitly how the bank treats your country of residence, income currency, employment type and tax documentation.

Mortgage valuation is not a structural survey

The bank’s valuation protects the lender’s security and helps establish the financing value. Do not treat it as a building survey, engineering inspection or legal due-diligence report. For an older, rural, renovated or unusual property, independent technical and legal checks can be particularly important.

Approval, offer and cooling-off period

Once the lender has approved the operation, read the personalised pre-contractual documentation carefully. Check the rate formula, instalment, TAEG, MTIC, term, insurance, commissions, linked products, guarantees and consequences of early repayment. Do not schedule an impossibly tight CPCV completion date: valuation, underwriting, documentation and the legally required mortgage-contract process all take time.

Early repayment and refinancing

Mortgage rules and temporary government measures can change. In particular, do not rely on older articles saying early-repayment commissions are universally suspended: temporary measures have had expiry dates. Check the current contract and Banco de Portugal’s Portal do Cliente Bancário before making a partial repayment, full repayment or transfer to another bank.

Before choosing an offer: compare these 12 things

  • Maximum approved loan and the bank valuation used.
  • Your actual cash contribution including purchase costs.
  • Fixed, variable or mixed rate and how long each period lasts.
  • Index and spread where variable.
  • TAEG and MTIC, not merely the advertised spread.
  • Monthly payment now and sensitivity to higher rates.
  • Loan term and age limits.
  • Life and multi-risk insurance premiums and where they may be purchased.
  • Account/card/salary or other linked-product costs.
  • Valuation, dossier, completion and mortgage-registration costs.
  • Early-repayment/transfer conditions.
  • Whether the approval and timeline fit the CPCV.
